  'gtk-can-change-accels' property is defined in gtkmenu.c. I could find
out
  the flag which corresponds to this. Now what I did is to allow the 
  keybinding for Home/End keys only if the flag is FALSE. Is it OK if I 
  implement it this way. Now for all kinds of menus, 
  if the flag is FALSE, the Home/End keynav will be enabled.

  g_object_get (G_OBJECT (gtk_settings_get_default ()),
                "gtk-can-change-accels", &can_change_accels,
                NULL);
  if (!can_change_accels)
  {
    gtk_binding_entry_add_signal (binding_set,
                                GDK_Home, 0,
                                "move_current", 1,
                                GTK_TYPE_TOOLBAR_DIRECTION,
                                GTK_MENU_DIR_FIRST);
   .....
  }    

Please give your thoughts on this.
